Wildcard Field Substitutions ($n)

A dollar sign followed by a digit n is replaced with the material that matched the nth wildcard in the pattern. The wildcards are numbered starting with 0. For example, the following entry would match the input string PSI%A::B and produce the resultant output string b@a.psi.siroe.com:

PSI$%*::*    $1@$0.psi.siroe.com

The input string PSI%1234::USER would also match producing USER@1234.psi.siroe.com as the output string. The input string PSIABC::DEF would not match the pattern in this entry and no action would be taken; that is, no output string would result from this entry.
